At only 24 weeks with my first py I'm having probs with my sleep. I start off determined to rest on my side and have tried a range of cushions to help but I always wake up on my back (my natural sleeping position) and the cushion is either at the bottom of the bed or has fallen out of the bed all together! I must be a restless sleeper! This is already meaning that I can wake up feeling a bit achy. Anyone else had a similar problem and does anyone know if it could cause problems in the third trimester if I carry on sleeping on my back?
